Oda is definitely cooking something with Tama's hat making abilities. He played this trivia about her and the fact that she came from the straw hat village extremely low-key during Wano (even thought that idea was clearly there since Tama's inspection given her foreshadowing during the summit war). Then, right before Tama got accepted as a strawhat we got a flashback about her hat making jobs that came out of nowhere, which then was followed by chopper bringing the topic of Tama's hats up in egghead and now it playing into the cover story plot during Elbaf, not to mention that Gaban has been show to wear them too.
Could it be that maybe Tama will make a new hat for luffy after he gives his back to shanks next time they meet? She could also just fix it to add to the long list of Luffy/Nami Luffy/Tama parallels there are. In any case this could even be the reason why Oda made Tama familiarize herself with the original straw hat in the first place.
